Abstract: Systems and methods are disclosed for cross-system user-level management of data objects stored in one or more information management systems, and for user-level management of data storage quotas in information management systems, including data objects in secondary storage. An illustrative quota manager is associated with one or more information management systems. The quota manager comprises a quota value representing the maximum amount of data storage allowed for a given end-user's primary and secondary data in the one or more information management systems. The quota manager determines whether data associated with the end-user has exceeded the storage quota, and if so, prompts the end-user to select data for deletion, the deletion to be implemented globally, across the primary and secondary storage subsystems of the respective one or more information management systems. Meanwhile, so long as the quota is exceeded, the quota manager instructs storage managers to block backups of end-user's data.

Abstract: In certain embodiments, a tiered storage system is disclosed that provides for failover protection during data backup operations. The system can provide for an index, or catalog, for identifying and enabling restoration of backup data located on a storage device. The system further maintains a set of transaction logs generated by media agent modules that identify metadata with respect to individual data chunks of a backup file on the storage device. A copy of the catalog and transaction logs can be stored at a location accessible by each of the media agent modules. In this manner, in case of a failure of one media agent module during backup, the transaction logs and existing catalog can be used by a second media agent module to resume the backup operation without requiring a restart of the backup process.

Abstract: Indexing preferences generally associate each data source with a type of indexing technology and/or with an index/catalog and/or with a computing device that hosts the index/catalog for tracking backup data generated from the source data. Indexing preferences govern which index/catalog receives transaction logs for a given storage operation. Thus, indexing destinations are defined granularly and flexibly in reference to the source data. Load balancing without user intervention assures that the various index/catalogs are fairly distributed in the illustrative backup systems by autonomously initiating migration jobs. Criteria for initiating migration jobs are based on past usage and going-forward trends. An illustrative migration job re-associates data sources with a different destination media agent and/or index/catalog, including transferring some or all relevant transaction logs and/or indexing information from the old host to the new host.
